I have a 51 plate Passat. 1.9 TDI PD.
My pink diagnostic socket is under the rubber strip beneath the handbrake.

I am looking to purchase a VAG COM cable from ebay but I am not sure which one to purchase.
I have seen some for between £9 and £15 and was wondering if these will do the job with the VAG COM software.

It doesn’t matter if it’s a USB or a serial cable connector (RS232).

Although not a mechanic, I would simply be using it every odd month to run a quick diagnostics ensuring everything with the car is working as it should be.
Or at the first moment something doesn’t feel right with it.

This way, I can inform my mechanic of the error code, let him verify the code and let him get on with any repairs.

Thanks.
